​if alpha and beta are zeroes of polynomial x2-4x+1.find the value of beta +1/beta

Dear student,

The given polynomial be p(x)=x2-4x+1Also, given that α and β are zeroes of polynomial Sum of zeroes, α+β=-coefficient of xcoefficient of x2=-(-4)1=4α+β=4      ...(1)Product of zeroes=α×β=constant termcoefficient of x2=11=1αβ=1    α=1β     ...(2)putting the value of α=1β in (1)1β+β=4 thus, the value of β+1β is 4
Regards
